REMOVABLE PARTITIGN FOR METAL-HEATING FURNACES.

Application filed October 3, 1919. Serial No. 328,163.

T 0 all whom it may concern:

Be it known that I, RICHARD .G. DRINKER, a citizen of the United States,residing at Quincy, county of Norfolk, and State of Massachusetts, haveinvented certain new and useful Improvements in Removable Partitions forMetal f Heating Furnaces, fully described and represented in thefollowing specification and the accompanying drawings, forminga part ofthe same. 7

This invention relates to a partition which maybe inserted removably inthe heatingchamber of a metal heatin -furnace to subdivide the spaceinto convenient compartmentswhich can be'heated and used separately whenthe furnace is not wholly required for heating long articles.

Such partitions are shown in application l lo/321,126 filed September 2,1919 for patent on open side furnace; and the present invention relatesto a particularconstruction for the partition by which it is providedwith detachable foot-plates to support it upon runways when thepartition 'isin use, and which may be stored separately and far morecompactly by separation from the partition when it is not in use.

The invention includes'various details of construction, which will beunderstood .by reference to the annexed drawing, in which Figure 1 is anelevation of a furnace with two partitions therein dividing it intothree separate spaces, the .door in; front of two such spaces beingraised or elevated to expose the interior to view; Fig. 2 is a crosssection of the furnace adjacent to ,a.partition supported on foot-platesthe door of the chamber being raised; Fig. "3 is a plan of the partsshown in Fig. 4 in section on line -33 in Fig. 1; Fig- 4 is asideelevation of the frame for one of the partitions mounted upon threedetachable foot-plates; Fig. 5 is an end elevation of the parts shown inFig. 4; Fig. 6 is a cross section of the frame f t e p r ion ken en n5-6 n Fig- 7 is an n er ed plan ef h etpl tes s own en th the pa tn-fram Fie- 4 and Fieis an ge view of one of as fe t-plate p e a g S leh n Fig. l.

nace which is of much greater width than length. Z) designates thepartitions mounted upright upon foot-plates which are supported uponrows of balls .(Z guided in runways 6 upon the floor. 7

The two partitions divide the heatingchamber a into three spaces whichare provided with separatedoors f, f. and f The doors f and f are shownraised in Figs. land 2. f

A combustion-chamber g is shown beneath the heating-chamber in Fig.Q'but' forms no part of the present invention, as it is immaterial tothis inventionhow the heatingchamber is heated.

Each partition is formed of a castemetal frame having a web it at themiddleof its thickness with flanges i projecting squarely from the webto both sides of'theipartit-ion.

The flanges cross the facesof the partition dividing it into variousspaces in which the TED STATE-S rnrnnrorrron. I

fire-brick or filler can be retained, whichis essential to preserve thepartition from destruction in theheating-chamber.

The web is formed with apertures j which connect the correspondingspaces 'upon .opposite sides of the web, and' permit fire.- bricks orfiller is to be extended through the apertures, as shown in Fig. 6, tolock together the refractory coating upon the'opposite sides of thepartition, by engagement with bricks is which are -laid directlyagainst'the web h..

When all the spaces are filled with bricks,

the partition is protected sufficiently for of the partition. A rib Zperforms the same function upon the foot-plate.

A narrow rib is employedto facilitate the pp ng eff o he i i nec s y tomake,

lie plate at having parallel ball raees pon thenndere de to lfit tworows of balls 91, which are movable in runways 11 upon the floor. Suchrunways extend transversely across the heating-chamber, and outside ofthe same far enough to draw the partition wholly from the chamber, whenit .can beremoved and stored until needed be fitted for again supportingthe partition by simply placing three of them contiguous over therunways supported: upon theballs therei11.,To prevent. the passage ofgases between the ends of the truck, a tongue 39 is formed upon one endof'each and a notch 9 upon the opposite end, such tongues and notchesinterlocking when the foot-plates are placed in proximity. r

It is understood that such trucks are adapted only to move in a straightline and to form a straight row when assembled, such as is shown in Fig.7, adapted to receive and transport the partition I). I

In the lower corners of the partition recesses' s are shownwith'transverse pin 11 in each, and such pins are provided to engage theoppositeends of a chain or sling; which would be hung from a crane andextended over'the upper corners of the partition to such pin forlifting'and moving the partition.

l-lolesr are shown perforating the frame near the middle of the topwhichmay be used for a similar purpose.

"It is evident that a single foot-plate of suitable length could be usedif constructed to receive 'and center the partition thereon the same asaplurality of foot-plates; but the plurality is preferable because itmakes. each part lighter for handling.

This is a material advantage, as suclrpartitions are not in use all thetime and take less room when stored if mounted detach ably upon thefoot-plates and if the foot plates themselves are relatively small so asto be moved with facility.

By the construction shown, the entire foot-plate consists of a singlecasting having parallel ball-races upon its under side, and a suitableseat upon the upper side to receive and hold a partition.

RA recess in the foot-plate to guide the setting of the partitionthereon is shown in the drawing formed by ridges 0 running along theedges of the foot-plate over the ball-races; but any other means may beemployed to form a loose detachableengage- Provision is also shown inFigs. 3 and 4: I

to prevent the passage of gases past the rear edge of the partition andserving at the same time to'steady the partition and hold it upright.

This provision consists of a vertical groove or recess a formed in therear wall of the furnace into which the rear edge of the partition ispushed when it is inserted in the heating-chamber, and which embracesits edges or corners with sufficient snugness to hold the partitionsteady-andprevent the passage of gases. i V

A plurality of trucks is desirable to support the partition so as topermit of the expansion of this supporting member.

Such expansion is permitted by placing the trucks with an open clearancebetween their adjacent ends, and the passage of gases between theseveraltrucks is prevented by the interengagement of the tongues 10 andnotches '9 upon the adjacent ends of the trucks.

It will be readily understood that a footplate greater in width than thethickness of the partition is necessary to sustain it upon the balls inthe runways nfland if such foot-plate were integral with the partitionit would prevent the piling of the partitions with their sides in closecontact when not in use in the heating-chamber. i p

The foot-plate shown herein is not adapted for any other purpose exceptto support the partition while in use in the furnace, and is thereforedifierent from ordinary trucks which may be used to carry miscellaneousarticles. I I i foot-plate shown herein is one of the elements whichoperates to entirely close the space between separate compartments ofthe" furnace, and has the rib Z projected from its lower-side for theexpress purpose of preventing the passage of gas beneath the partitiom vj i Having thus set forth the nature of the invention what is claimedherein is: V

1. In a metal-heating furnace having runways extended transversely ofthe heating-chamber, foot-plates. having ball-races corresponding to therunways and seats in alinement upon the tops of the foot-plate,

and a partition fitted to the seats upon the runways and supportedthereby in working 7 position within the heating-chamber.

2. In a metal-heating furnace having runways extended transversely ofthe heat ing-chamber, a partition provided with a plurality of means forsupporting it movably upon the runways such means having recesses inalinement with one another upon their upper sides adapted to "receiveand center the partition and being detachable from the partition whenremoved from the heating-chamber for storage.

3. In a metal-heating furnace having runways extended transversely ofthe heat ingchamber, a partition provided with plurality of interlockingdetachable footplates for supporting it movably upon the runways, suchfoot-plates having recesses in alinement with one another upon the uppersides adapted to receive and center the partition, and ribs upon theirunder sides to prevent the passage of gases.

l. In a metal-heating furnace having runways extended transversely ofthe heating-chamber, a partition provided with means for supporting itmovably upon the runways and the rear wall of the furnace having avertical recess adapted to receive the rear edge of the partition whenpushed thereinto and to then retain the partition in a verticalposition.

5. A removable partition for a metal heating-furnace, comprising a framehaving a central web with flanges projected squarely therefrom at theedges and across its flat sides, and apertures through the-web betweenthe crossed flanges for binding together the refractory material uponthe opposite sides of the web.

6. A removable partition for a metal heating-furnace, comprising a framehaving a central web with flanges projected squarely therefrom at theedges and across its sides the frames thickness corresponding to thelength of a fire-brick, apertures through the web between the crossedflanges, and fire-brick extended transversely through the apertures forbinding together the refractory material upon the opposite sides of theweb. a I

7 A removable partition for a metal heatingfurnace, comprising arecessed frame having its recesses filled with refractory material andsockets in the ends of the frame with transverse pins fitted to engagemeans for lifting the frame from the truck when required.

In testimony whereof I havehereunto set my hand.
